the filterExpression on AbstractSchemaManager seems not to work for sequences.

This only happens under postgres.

It seems the way the sequences are handled are the culprit: It tries to get min_value etc of sequences without matching sequence names to the filter expression in advance.

If for example access to the sequences is denied, (Different schema without permissions for the current entity manager), any higher-level ORM operations like generating migration versions fail.

--------------------- UPDATE

the context is when using migrations. Positive regexp expressions do not limit the migration to a single schema. eg ^schemaname.$
Instead, all sequences on the current database are returned.
When trying to limit a migration to a single schema consecutively this doesn't work.
We are using a per-schema connection, so this results in a lot of hassle for us.

I believe we are bumping into the same issue. Our webapp uses Migrations, but for our webapp we are limited to a certain schema within a bigger PostgreSQL database. We only have permissions on our own schema and public.
Now, listSequences in AbstractSchemaManager does filter the asset names correctly with the mentioned fix.

But the problem is with the step before, _getPortableSequencesList (see line 135 of AbstractSchemaManager):

This function goes out and does a _getPortableSequenceDefinition on every sequence in the unfiltered list. For every sequence, the _getPortableSequenceDefinition in PostgreSqlSchemaManager performs a SELECT:

I currently have a workaround running locally, which filters the sequences list before creating the PortableSequence's. This is probably hackish and a poor workaround, just posting here as a temporary solution and further illustration of the problem.
